Question about RPM Super T56
Shift quality?
Durability?
Opinions?

"We upgrade the blocking rings to compressed carbon on all our units and micro polish all the internal parts on our Level 5s. That helps the high RPM shifting significantly, but with any synchronized transmission at that high RPM it is making the blocking rings do a LOT of work to change the speed of the clutch disk, input shaft, cluster gear and the next gear you are shifting into. If you are going to do a lot of high RPM shifting and don't want to go to a faceplated unit. I would recommend having a tripple cone M6 built. We have done quite a few. I would really like someone to pull the trigger on our Super T56. It uses all C6 Z06 tripple cone internals with a 1 piece cluster gear and a 32 spline SSR mainshaft. I nick named it the Super T56 as a throw back to the old Super T-10."
"A tripple cone M6 would come in around $2895 and a Super T56 would be $3495. Both of those prices reflect the different in the price of the f-body core that woule be returned. The tripple cone parts are a good bit more expensive than single cone. I agree 100% about autos being boring"

Its a lot of money for that trans and I really want to make sure i make the right decision on which built trans to go with. I dont like charging my parts on credit cards and would take me 5-6 months to save up enough extra money to buy this one.
I definitely would've upgraded to this instead. How many rpms can this thing take? I'm guessing over 7R's since the stock z06 redline is 7k. Anyone know the torque limit?

today, great company and easy to deal with highly recommended!!!!!!
thanks jeremy for your help
I know who's not eating at Olive Garden this week!
As for the Super T56 like AJ said it is for all intents and purposes a C6 Z06 T56 with an f-body/GTO style front plate, tail housing and mainshaft. We have had fantastic luck with all of our C6 Z06 T56 transmissions. We have decided not to use the SSR 32 spline shaft tho. We are going to use a G-force 9310 mainshaft to retain good wall thickness of the yolk. The larger the diameter of the splines the thinner the wall of the yolk will be because you can only go so big with the hole for the output shaft in the tail housing.
